I don't think the Balmars show anything on the tach unless the field is hot. If there's no current going in, then you'll get zero on the tach (often get a zero on start-up due to delayed cut-in).
Try turning on some good current hogs like lights and fridges to get the alternator
to kick in. Your tach should come to life.
